Definitions

  • the invention relates to a biologically degradable heat-insulating material which contains, inter alia, cellulose and/or wood fibres and bico-fibres, that is two-component fibres as binders.
  • the present invention further relates to a wood-fibre heat-insulating material which exhibits a heat-insulating property, a thermal stress-relieving property, a sound-damping and fire-retarding property, a fire-resistance property, a sound-damping property, preferably an ant-repelling property, a moisture regulating property, an environmental protection property and detoxification properties.
  • the invention further relates to a method for producing a heat-insulating material by the combined application of a dry method and a semidry method.
  • Wood fibre boards comprise a soft fibre board (insulating board) having a density of less than 350 kg/cm 3 and produced by a wet process which uses sludge in which wood fibres, binders and size are dispersed in water, as in paper manufacture, a medium-density wood fibre board (MDF) which is produced by spraying an aqueous solution containing wood fibres, a melamine resin binder and a water-repellent agent to be applied with adhesive bonding strength, and by drying the solution by a dry method using a heating press, and furthermore a hard fibre board (hard board) having a density of 800 kg/m 3 or more which is press-formed by heating at high pressure. These boards are used differently in the household as construction materials and furnishing materials.
  • MDF medium-density wood fibre board
  • the unexamined Japanese Patent Publication No. 2001-334510 describes a cost-down technology whereby MDF boards having a low density are achieved whilst saving energy by forming a mixture containing wood fibres and a thermoplastic resin binder into a fleece and thermally fixing the binder at a temperature higher than its softening point.
  • the unexamined Japanese Patent Publication No. 2002-337116 describes a process in which MDF is dipped in an aqueous solution in which polyethylene glycol, a triazole ant repellent and ammonium phosphate in a phenol resin form a mixture in order to make the MDF flame-retardant and insect-proof.
  • the unexamined Japanese Patent Publication No. 2003-311717 describes a recycling method by which means recycled material having a density of 50 to 250 kg/m 3 and a fineness of 0.01 to 20 mm, obtained by crushing a used wood fibre board, is mixed with the raw material of the MDF.
  • the unexamined Japanese Patent Publication No. 2006-289769 describes a method for producing MDF having a weight per shot of 400 to 2500 g/m 2 and a thickness of 2 to 50 mm by laminating a nonwoven obtained by mixing the fibre polylactate with cellulose fibre having an average fibre length of 5 to 100 mm.
  • the aforesaid improvement technologies pertain to the improvement technologies of an insulating board which is produced by a wet process or to those of MDF produced by a dry process, and each of these technologies corresponds to the thermal insulation, non-flammability, insect resistance, energy saving, cost reduction and the measures for recyclability but the present situation is such that no forming methods and manufacturing methods have been achieved with this, whereby the problems can be comprehensively resolved.
  • the present invention provides for properties such as elasticity, mechanical strength, sound damping, flame retardance and fire resistance as well as ant repellence such as have not been found previously in an insulating board produced by a wet process, even though the density range is similar to that of an insulating board produced by the wet process and the semidry process, and it improves the thermal insulation, moisture regulating property and the measure against unhealthy living and a diseased environment.
  • the flame-retardant and fire-resistant properties its performance features are equivalent to or more than equivalent to a glass wool heat-insulating element and a rock wool heating insulating element and likewise with regard to the thermal insulation, a thermal stress-relieving property which delays heat transfer in an unstable state, which is not observed in a foam heat-insulating element, and a high thermal insulation are made possible by an airtight adiabatic construction.
  • used heat insulating material according to the present invention is used as fertilizer fleece in agriculture and forestry and contributes to the activation of forests and detoxification of the environment and forms a measure against global warming.
  • a felt-like heat insulating material according to the present invention can be subjected to a secondary utilisation by a moistening form pressing and hot forming and, when used as an ecological interior material for automobiles, contributes to the development of a new field.
  • the present invention comprehensively solves the aforesaid problems by means of a heat-insulating material having a density of 300 kg/m 3 or less, which is the same as that of an insulating board produced by a wet method, wherein a mixture produced by a wet method and a semiwet method is used as the main material, said mixture comprising a wood fibre having an average fibre diameter of 1 mm or less and an average fibre length of 20 mm or less and a biologically degradable binder which swells in hot water and fixes due to heat, having a fineness of 10 dtex and a fibre length of 20 mm or less.
  • the heat insulating material produced by the method of manufacture has a low density and elasticity and as result of the airtight adiabatic construction which uses a thermal stress-relieving property due to a low thermal conductivity and a high thermal capacity and elasticity, provides high thermal insulation and sound damping such as has not been found previously in inorganic staple fibre heat-insulating material such as glass wool or foam heat-insulating material such as extruded and expanded polystyrene.
  • the wood fibre which is treated with a flame-retardant, ant-repellent agent which is doubled with a fertilizer component furthermore forms a carbonised heat-insulating layer against ignition by fire and heat on the surface of the heat-insulating material and is self-extinguishing, a wall element combined with a plasterboard and the like shows excellent fire-retardant and fire-resistant properties.
  • the raw materials of which the heat-insulating material is composed are biologically degradable and since the flameproof ant-repellent agent contains the three fertilizer elements for plant cultivation, they can be used, including the waste from used insulating materials, as fertilizer material without any loss due to transplanting. They also exhibit an environmental cleaning function which contributes to accelerated growth of seeds activation of forests, reduction of CO2 and prevention of global warming.
  • FIG. 1 is a flow chart of the preferred method of the invention.
  • Wood fibre forming the heat-insulating material according to the invention is obtained by treatment of thin timbers such as conifers, for example, silver fir, Asibrica, Japanese larch, cedar and spruce and broad-leaved trees such as beech, maple and sawtooth oak; wood chips from old timbers and ground tough bark of bamboo, hemp and the like with flame-retardant ant-repellent agents, doubled with a fertiliser component, and fibrillation thereof.
  • thin timbers such as conifers, for example, silver fir, Asibrica, Japanese larch, cedar and spruce and broad-leaved trees such as beech, maple and sawtooth oak; wood chips from old timbers and ground tough bark of bamboo, hemp and the like with flame-retardant ant-repellent agents, doubled with a fertiliser component, and fibrillation thereof.
  • the wood chips and ground products are obtained by cutting timbers into the form of thin pieces having a length of 10 to 30 mm and a width of 5 to 15 mm and treatment thereof with a refining agent described subsequently.
  • the wood chips and ground products treated with a flame-retardant ant-repellent agent are treated with steam and softened by steam or the like, and then shredded by a refiner so that they have an average fibre diameter of 1 mm or less and an average fibre length of 20 mm or less, and further processed into wood fibres.
  • the reason for an average fibre diameter of 1 mm or less is to ensure elasticity of the heat-insulating material obtained and to reduce its thermal conductivity.
  • the reason for an average fibre length of 20 mm or less is to suppress granulation of adjacent fibres and the production of fluffs during a mixing step with a fibrous binder described subsequently in a dry process and the uniform mixing thereof by dispersion. Uniform dispersion is appropriate in a range of 10 to 300 L/D (fibre length/fibre diameter) and the fibre length is preferably 20 mm or less.
  • the flame-retarding ant-repellent agent doubled with a fertiliser component which is the main component of the heat-insulating material of the present invention is mixed in a state in which a dip treatment of the wood fibre is carried out.
  • the flame-retarding ant-repellent agent doubled with a fertiliser component gives the heat-insulating material according to the present invention a flame retardance and non-flammability and a composite element with a plaster board and the like, a fire-retardant and fire-resistant property and it provides for an ant-repelling property as a measure against termite erosion.
  • the flame-retarding ant-repellent agent is doubled with a fertiliser component which can be used as a fertiliser fleece and as matting for the cultivation of seedlings in agriculture and contains used heat insulating material.
  • the flame-retarding ant-repellent agent doubled with a fertiliser component is a mixture of a boron compound and a phosphorus compound and especially contains boric acid, borax, borosilicate, ammonium polyphosphate, ammonium dihydrogen phosphate, magnesium polyphosphate, potassium polyphosphate, sodium hypophosphite and sodium sulphite as solution aid and potassium carbonate and magnesium chloride as fixing aid. If an immersion-adherent quantity for the wood fibre is 2 wt.
  • the flame-retardant effect and the ant-repellent effect are inadequate and at 30 wt. % or more, a saturation effect occurs, which results in increased expense which is why 2-30 wt. % is considered to be appropriate.
  • the biologically degradable binder forming the main component of the heat-insulating material according to the invention is a natural and synthetic binder and comprises a mixture of hot-water-soluble adhesive binder which is suitable for a wet method and for a semidry method and a hydrophobic thermally fixing binder and is restricted to a biologically degradable binder in fibre form.
  • the natural and the synthetic hot-water-soluble binder contains a natural starch, cellulose derivative and chitosan and the hot-water-soluble binder contains ideally saponified polyvinyl alcohol, a silicon-containing polyvinyl alcohol and the like. It corresponds to a binder that is fibre-supported, for example, by wood fibres or a fibrous binder.
  • the synthetic hydrophobic thermally fixing binder contains polycaprolactam polyamide, polylactic acid, aliphatic polyester resins such as polybutylene succinate, polybutylene succinate adipate and a biologically degradable polyethylene polypropylene composite resin that is fibrous.
  • the fibrous binder is restricted to a fibre-supported type of binder, having a fineness of 10 dtex or less and a fibre length of 20 mm of less, or to a fibrous binder in order to ensure homogeneous mixing of the raw material by dispersion, the degree of fineness of the mixture and the property of a flaky deposit and a distribution in the dry method and the semidry method which are the forming methods of the present invention.
  • the main component of the composition according to the present invention comprise the wood fibres, the flame-retardant ant-repellent, doubled with a fertilizer component and the biologically degradable hot-water soluble and thermally fixing fibrous binder which has been explained previously.
  • a suitable mixture can be produced from environmentally friendly additives such a water-repellent fluorochemical agent, a water-repellent silicone oil agent, alkyl ketene dimer as bonding agent, an anti-bacterial agent in which antibacterial substances such as copper and zinc [using] calcium phosphate as carrier and fungicides such as hinokitiol and chitosan as further additives.
  • a fleece and a light-weight building board made of the heat-insulating material according to the invention can be produced by a method in which the dry method and semidry method described hereinafter are used in combination, wherein this fleece and this light-weight building board differ from the insulating board produced by a wet method and by the MDF board produced by a dry method.
  • the method of manufacture according to the present invention is shown in the flow diagram in FIG. 1 .
  • Wood chips 1 having a length of 15 to 25 mm, a width of 5 to 10 mm and a thickness of 2 to 5 mm, obtained by peeling the outer tree bark of thin timbers and old timbers of conifers and broad-leaved trees which are dipped at 6 in an aqueous solution or suspension containing a boron compound and a phosphorus compound at a normal temperature of up to 80° C. for a duration of 2 to 24 hours, are treated with steam at a vapour pressure of 0.5 to 1 MPa for a duration of 5 to 20 minutes and at 8 are successively defibrillated using a single- or two-disk refiner.
  • the average fibre diameter, the average fibre length and the output rate of the wood fibres can be controlled by varying the rotational speed of the refiner and by varying the distance between the fixed blades and the rotating blades.
  • a first binder 2 that is biologically degradable can optionally be added to the wood chips 1 .
